USB output on latest Bluesound Node

I have the latest Bluesound Node, not the X, and it has  the usb output. I normally  run coax from it to my Oppo 205. Out of curiosity I thought I would try the usb output because some people claim better sound from the usb.  Well I get absolutely no sound when plugged into my Oppo 205 usb input.  I know I’m not the only one with this issue as an online search shows other people with the same problem. I tried changing some settings but no luck. Seems like what I can gather it’s just not compatible with some DACs for whatever reason.  I contacted Bluesound about it and they were very quick to respond but could not offer a solution to this issue.  Not a problem as I’ll just continue to use the coax but just curious if anyone here had the same issue and if they managed to correct the problem.
